He flies out of a 2500' elev., relatively short strip that requires downwind landings most of the time. He has a 10 knot lower stall (and approach speed) "crisp ailerons and roll control near the stall". "No noticeable reduction in cruise speed, 160 knots indicated at 12-13k, 195-200 knots ground speed." "Can't use full flaps (not enough pitch trim), but 15 -20 degrees is fine for a stable approach with good elevator authority." He bought them from Pacific NW Aero in Bend, OR http://www.pnwaero.com/Lancair.htm Steve Colwell LEG2 N15SC reserved Michael, why would you want to destroy the laminar flow the wing was designed for?
